Abstract

The invention discloses a fired brick made of manganese slag and a preparation method thereof, comprising the following raw materials in parts by weight: 100-150 parts of manganese slag, 60-80 parts of papermaking sludge, and 5-10 parts of redispersible latex powder , 4-6 parts of rosin resin and 5-8 parts of boron oxide. The sintered brick of the present invention uses manganese slag and papermaking sludge as the main raw materials, provides an effective way for the comprehensive utilization of solid waste, reduces environmental pollution, protects clay resources, is beneficial to the sustainable development of human beings, and has high economic value . The sintered brick of the invention also has the advantages of high strength, low water absorption, low density, good heat preservation and heat insulation effects, wide source of raw materials, low cost, simple preparation process, low energy consumption, etc., and has a good market prospect.

Description

technical field [0001] The invention belongs to the technical field of new building materials, and specifically relates to a sintered brick made from manganese slag and a preparation method thereof. Background technique [0002] Manganese is an important basic material in the national economy and one of the country's important strategic resources. At present, my country has become the world's largest producer, consumer and exporter of electrolytic manganese. As an important metallurgical and chemical raw material, electrolytic manganese has made great contributions to my country's industrial development and regional economic construction. However, the electrolytic manganese industry, as a typical hydrometallurgical industry, has also caused serious environmental problems during its rapid development. Pollution, especially the pollution of electrolytic manganese waste slag, according to statistics, the amount of acid leaching slag discharged per 1 ton of electrolytic manganese...
